Can someone please explain how to find the difference -7 - (-8)

Answers

Answer 1

Answer:

1

Step-by-step explanation:

In the equation -7 - (-8), there are two 'minus' signs; we can convert two minus signs into a plus sign according to the 'minus minus equals plus' rule, that would make the equation (-7) + 8 for which the answer is +1.

Answer 2

Answer:

1

Step-by-step explanation:

-7-(-8)

First you should solve the brackets.Remeber (-) minus into (-) equal (+)

therefore;

  -7-(-8)= -7+8

when there is a minus and a plus you should minus the two numbers and put the largest value sign.

therefore;

   -7+8= 1

Hope you understand.If you have any problem just ask me I will solve it.

(1) Combining fractions is just a matter of writing each individual fraction in terms of a common denominator. The least common multiple of 6, 4, and 8 is

LCM(6, 4, 8) = 24

since 6×4 = 4×6 = 8×3 = 24. So

2/6 = (2×4)/(6×4) = 8/24

1  1/4 = 4/4 + 1/4 = 5/4 = (5×6)/(4×6) = 30/24

13  4/8 = 104/8 + 4/8 = 108/8 = (108×3)/(8×3) = 324/24

Then

2/6 + 1  1/4 + 13  4/8 = 8/24 + 30/24 + 324/24 = 362/24 = 181/12

(2) We have

LCM(12, 9) = 36

since 12×3 = 9×4 = 36. Then

121  2/12 = 1452/12 + 2/12 = 1454/12 = (1454×3)/(12×3) = 4362/36

Answer:

-36

Step-by-step explanation:

We have the equation 4 lm - nl , along with the values, m is equal to -7 and n is equal to 2.

To solve, we need to only substitute the values of each variable into the original equation :

4 |-7 - 2|

First solve the equation within the absolute value, any value that comes out of those brackets become positive :

|-7 - 2|

|-9|

4|-9|

4(-9)

Now multiply to get our answer:

4(-9)

Heya!

Answer:

h = √91 cm

Step-by-step explanation:

Apply pythagorean theorem, a² + b² ° c².

Where,

a = ½(6) = 3 cm

b = h

c = 10 cm

Plug in the values

3² + h² = 10²

9 + h² = 100

9 + h² - 9 = 100 - 9

h² = 91

Estimating Irrational Numbers​

Answers

The idea here for estimating square roots is to pin the number under the radical (2 in this case) between two perfect squares.

2 is between 1 and 4.

sqrt(1) = 1 and sqrt(4) = 2.

Since 2 is between 1 and 4, sqrt(2) is between sqrt(1) and sqrt(4).

This means sqrt(2) is between 1 and 2.

Answers

Answer:

2:1.

Step-by-step explanation:

The area of a red  curved surface = 2πr^2.

The area of the yellow flat surface = πr^2.

This is the case for all the hemispheres.

Therefore the  required  ratio =  2πr^2 :  πr^2

Answers

Answer:

 NO = 10

Step-by-step explanation:

The segment addition theorem tells you ...

 MN + NO = MO

Substituting the given expressions for these lengths, we have ...

 x + 5x = 3x+6

 3x = 6 . . . . . . . . . subtract 3x

 x = 2 . . . . . . . . . . divide by 3

Find the equation of the line perpendicular to the 13x-3y=9 and passing through (-5,0)

Answers

9514 1404 393

Answer:

  x +4y = -5

Step-by-step explanation:

The equation of the perpendicular line can be found by swapping the x- and y-coefficients and negating one of them. The new constant can be found by substituting the point values into the equation.

  3x +12y = 3(-5) +12(0)

  3x +12y = -15

We notice that all of the values include a factor of 3. We can divide that out to put the equation in standard form:

  x + 4y = -5

Students noticed that, since the time that grass began to grow on a barren hillside, and water seemed to wash down the slope into the school yard during a rainstorm . The students thought that the grass helped hold the soil in place on the slope. The students predicted that more soil would wash down a slope without grass than a slope covered with grass. To find out if they were correct , the students conducted an experiment with three identical rectangular pans of soil. In pan 1 they planted grass seed and allowed it to grow to several centimeters tall. The students filled pan 2 with only soil.
